During trenching and excavating, what is the minimum clear unobstructed distance from the trench edge to the dirt or spoil pile?

• A. 2'
• B. 1'
• C. 3'
• D. 4'

Answer: (A)

Keep the dirt or spoil pile at least two feet away from the trench edge. This distance helps prevent material from falling or sliding back into the trench, keeps a safe space for workers to maneuver and retreat, and protects the trench walls and any supporting systems. One foot would be too close and increase the risk of material entering the trench or crowding the work area; three or four feet are safe, but they’re not the minimum required—two feet is the required minimum.
